About Converting Liter per Days to Cup per Days
Liter per Days and Cup per Days both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
cup per days = liter per days × 4.22675283773
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per days equals 1.157407e-8 base units, and 1 cup per days equals 2.73829e-9 base units, so dividing one by the other gives the direct liter per days-to-cup per days factor of 4.22675283773.
Simple example
1 L/d × 4.226752838 = 4.226752838 cup/d
1 liter per days = 4.226752838 cup per days.
Real-world example
60 L/d × 4.226752838 = 253.6051703 cup/d
60 liter per days = 253.6051703 cup per days.

Frequently asked questions
How many cup per days are in 1 liter per days?
1 liter per days equals 4.226752838 cup per days, using the exact defined conversion factor rather than an estimate.
How do I convert liter per days to cup per days?
Multiply the liter per days value by 4.226752838. The converter above does this instantly to whatever precision you set.
How do I convert cup per days back to liter per days?
Use the reverse factor: 1 cup per days equals 0.2365882365 liter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per days?
Liter per Days (L/d) is a unit of flow rate.
What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
Is the liter per days to cup per days conversion exact?
Yes. Both liter per days and cup per days are defined by fixed standards rather than physical artifacts, so the factor of 4.226752838 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
